In a method and apparatus for the electronic distribution of digitised information on demand, remote and/or local mass data stores are used to store digitised information for use in the generation of products such as software media. Available products and related information can be searched, browsed and requested at a local fulfilment unit; or requests can be made remotely. The products generated and associated packaging, certificates of authenticity, instruction manuals and licence numbers may optionally include customer specific information, and customer given personalisation. Additional security features include storing essential parts of the digitised information remotely so that products can not be generated using only locally stored information; and recording the digitised information on the at least final segments of longer than standard format CDs preventing complete copies onto CDs of standard format.
